Not too long ago, I made a long desk pen from a PSI Premium Designer NT kit. I used two blanks. The first was cut to the length of the lower tube, but I left the second one 5-inches long and only drilled deep enough to accomodate the upper tube. I prefer the Premium Designer over the "Regular" Designer's because it uses a Parker type refill.
On this first one I used the center band from the kit; however, the next time I make one, I will be eliminating the center band and simply drilling a shallow counterbore in the upper blank instead. Sort-of merging two modifications into one.
This is the "Long - Closed End" Premium Designer NT that I made as a Desk Set.
This is the Premium Designer NT with the "No Centerband" modification.
With the extra length (closed end) and the "mostly wood" construction without the center band I think it might be shaped to make an attractive magic wand that incorporates a pen.
